Assess understanding of the core constructs of the Transtheoretical Model (stages of change, processes), Social Cognitive Theory (self-efficacy, outcome expectations, observational learning, reciprocal determinism), and Self-Determination Theory (autonomy, competence, relatedness, types of motivation) and how these constructs inform strategies to promote and tailor physical activity interventions, measure readiness and motivation, and select behavior-change techniques for adult learners.
